What developers say about LocoAI

Real reviews from real users using LocoAI with AI translation providers.

★★★★★

Hey guys. Just wanted to say THANKS for this plugin. I started manually translating a thing, and I had over 1000 entries to edit, words/sentences. A few clicks and this plugin shaved the time allocated to like NOTHING.

Excellent plugin for bulk translations. It has saved me a lot of time translating theme and plugin strings quickly and efficiently.

Loco Translate is already an essential tool for translations in WordPress, but translating every single word one by one can be very time-consuming. Thanks to Automatic Translate Addon For Loco Translate.

OpenAI charges roughly $0.10–0.30 per 1,000 words translated, depending on which GPT model you choose. For a typical small WordPress site (50–100 pages), that's usually under $5 in one-time API costs. There are no per-translation fees from us — you only pay OpenAI directly for what you use.

Yes — translation requires a paid OpenAI API account, which is separate from a ChatGPT subscription. Most users top up $5–10 of credit and that covers hundreds of pages. Sign up and add credit at platform.openai.com.

We support GPT-4o, GPT-4 Turbo, GPT-4, and GPT-3.5 Turbo. We recommend GPT-4o for the best balance of quality and cost — it's the latest flagship model and produces the most accurate translations across all languages.

Your API key is stored encrypted in your WordPress database and is only used server-side. Translation requests go directly from your WordPress site to OpenAI — we never proxy or store any of your content or your API key.

Yes. The plugin supports OpenAI, Gemini, Claude, DeepL, Google Translate, and Yandex (depending on which plugin you're using). You can switch the active provider any time from the plugin settings — already-translated content stays as-is.

Yes — our plugin sends WooCommerce product data, ACF custom fields, and Yoast/RankMath SEO meta through OpenAI for translation, then writes the translated values back to the right WordPress fields. HTML and shortcodes are preserved automatically.
